I really don't like the Shottenheimer hiring much, but I don't see any big reason for all the meltdowns here. Mike is no big loss. He was never going to outcoach a good coach in a big game with equal or better talent. He hit his absolute ceiling.
Now at least the Cowboys will have a shakeup in the staff, and that was badly needed. It's a shame the old OC is now the HC, but at least he's not the OC. Perhaps the new OC hire will add some more dimensions to the offense.
That's about as optimistic as I can get. I'm hoping for some good hires, not expecting a magical resurgence that leads the Cowboys to the Superbowl. But at least there is some change, and the Cowboys needed change. It may be shitty change for the worse, but something needed to happen. The other options were not overwhelming, either. It was pretty much "choose the form of your destructor" and we just go rid of the fucking Marshallow Man.
Draft some badasses and let it all roll and see what happens.
